中国GF-1、GF-6-WFV正射影像数据集（2018）

针对研究区域提供时相为2018年WFV传感器正射影像数据共690景，涉及遥感卫星有GF1、GF6号。所提供数据均为L1A产品基础上的正射处理数据，通过在影像上选取控制点，并利用已获取的范围内的数字高程模型(DEM)数据，对影像同时进行倾斜改正和投影差改正。

A total of 690 orthorectified image scenes captured by the Wide Field View (WFV) sensors in 2018 were provided for the designated research area. The remote sensing satellites involved are GF-1 and GF-6. All provided datasets are orthorectified products derived from the original L1A products. Tilt and projection errors of the images were simultaneously corrected by selecting ground control points (GCPs) on the imagery and leveraging the acquired digital elevation model (DEM) data within the study region.
